RF4 PWM/N
Multifrequency PWM series
One controller for any mains, anywhere in the world. The RF4 PWM/N is the wide-input digital multifrequency version of the RF4 PWM, running on 80–260 V while digitally regulating amplitude and frequency and searching out the feeder’s resonance frequency for maximum performance and reduced consumption.
It drives linear and bowl feeders up to 5 A, at 50/100 Hz ±12 Hz (/BN and /BDN versions) or 30–130 Hz (/STN and /KN versions), 3000/6000 vpm, with PLC automatic input (0/10V-4/20mA; not on the /KN version), NPN/PNP or relay sensor control and adjustable ON/OFF delay. Available with display, keys, single potentiometer or as a bare DIN35 circuit, and up to IP65 (NEMA 4/4X) in the boxed version.
Description
Microprocessor digital professional controller with visualized frequency (optional). This controller is available in a metallic box with two potentiometers and display, with keys and display, with a single potentiometer without display, or as a circuit on DIN35. Wide-mains 80/260 V version of the RF4 PWM.
Application: digital regulation of linear and bowl feeders till 5 Amps. The RF4 PWM/N optimises feeder operation by searching for its resonance frequency (maximum performance), eliminating its lengthy and difficult mechanical calibration.
